Multi-look SAR processing with road location and moving target parameters estimation

Multi-look processing is a well-known technique actively used in the SAR research community. In the paper, a method is described for the extraction of the ground moving targets parameters from a sequence of SAR look images obtained with a single-antenna SAR. The method calls for the automatic road extraction from the multi-look SAR images. The proposed road detection and location algorithm is based on the Canny edge detector and the histograms of image gradient directions. The estimated road coordinates are used for unambiguous evaluation of the moving targets parameters, namely the velocity components and the coordinates.
